HDDs unreadable after overclock

[alizee]

So, with my new motherboard (P5N32-E SLI Plus), older e6300 (from October) and some old hard drives (PATA) my system will overclock fine to 2.8GHz, but once I go even 7Mhz beyond that my HDD either fails a checksum (generally) or just doesn't get seen (only once). I booted to Knoppix on my SATA DVD-RW and that worked fine, so it seems like it's a PATA problem. Does anyone have a solution or even just somewhere to start looking? The long term solution is to get a SATA HDD for the system, but that's a little ways off (like a month or so). I'd like to do something that's free.

It's kind of reminiscent of my 2.4C P4, I could get it to overclock to 3.2GHz in software, but once I took it past a 240MHz FSB in the BIOS it wouldn't see my SATA HDD, but I could boot fine to my PATA DVD-RW. Funny how it's opposite, eh?

Thanks in advance

Start with raising your RAM's timings to 5-6-6-18, and I'm willing to bet that the point where that happens will magically be higher.

how about that. I had been running at 5-5-5-16, then set it to auto (which ended up being 5-5-6-17) and got to 3150MHz. I'll play around with it some more.

Thanks man.
